# Working with private channels using third-party tools

In order to access private channels via third-party tools (such as pip, Twine, or R), you must have a user token. This can be done through the conda repo tool or by [creating channel-specific, read-only/read-write tokens via UI](./auth_token#create-a-new-user-authorization-token).

## Python packages

### Uploading

Twine is a popular tool for uploading Python packages to PyPI-like repositories. Run the following command to upload Python packages:

```sh theme={null}
twine upload --repository-url http://<DOMAIN>/api/repo/<CHANNEL>
<PACKAGE> -u <TOKEN> -p x-auth-token
```

**Example**

```sh theme={null}
twine upload --repository-url
http://demo-repo.com/api/repo/my-pip-channel six-1.13.0-py2.py3-none-any.whl -u 46e98d3dbf2378bb26e2107867652ee734eb098ea5b96f35 -p x-auth-token
```

If the token is incorrect, you will receive a 401 error message.

Please refer to the [Twine package documentation](https://twine.readthedocs.io/en/latest/#configuration) to learn how to configure your username and password via the configuration file or environment variables.

### Installing

Similar to pip, Anaconda Server supports user authentication using Basic Authentication. The following is the proper format for installing pip packages:

```sh theme={null}
pip install --trusted-host <DOMAIN> --index-url
http://<TOKEN>:x-auth-token@<DOMAIN>/api/repo/<CHANNEL>/simple <PACKAGE>
```

<Note>
  `x-auth-token` is not a placeholder, but is used as the actual password for Basic Authentication.
</Note>

**Example**

```sh theme={null}
pip install --trusted-host demo-repo.com --index-url
http://46e98d3dbf2378bb26e2107867652ee734eb098ea5b96f35:x-auth-token@demo-repo.com/api/repo/alex-pip/simple six
```

Make sure to add a trusted host.

Please refer to the [pip documentation](https://pip.pypa.io/en/stable/user_guide/#configuration) to learn how to configure the index URL via the configuration file or environment variables.

## R packages

### Uploading

Since there is no standard tool for uploading R packages, you can use either the UI or API directly. Run the following command to upload R packages:

```sh theme={null}
curl -v -F filetype=cran_source_package -F content=@<FILENAME>
http://<DOMAIN>/api/repo/<CHANNEL> -H"X-Auth: <TOKEN>"
```

Where `<TOKEN>` is the `x-auth-token`.

**Example**

```sh theme={null}
curl -v -F filetype=cran_source_package -F content=@abc_2.1.tar.gz
http://demo-repo.com/api/repo/alex-pip -H"X-Auth: 46e98d3dbf2378bb26e2107867652ee734eb098ea5b96f35"
```

Please use `cran_source_package` for source packages and `cran_binary_package` for binary R packages.

### Installing

You can use your domain as a repository URL in the `install.packages` function by injecting a token into the path:

```sh theme={null}
http://<DOMAIN>/api/repo/t/<TOKEN>/<CHANNEL>/cran
```

This may look something like the following:

```sh theme={null}
http://demo-repo.com/api/repo/t/46e98d3dbf2378bb26e2107867652ee734eb098ea5b96f35/alex-pip/cran
```

**Example**

```sh theme={null}
> install.packages("abc", repos="http://demo-repo.com/api/t/46e98d3dbf2378bb26e2107867652ee734eb098ea5b96f35/repo/alex-pip/cran")
```
